Ingredients
For the Shortbread Crust & Streusel Topping:
- All-purpose flour: 2 1/4 cups (295 g)
- Granulated or caster sugar: 2/3 cup (134 g)
- Salt: 1/2 teaspoon
- Unsalted butter: 7 oz (200 g) cold, divided (approx. 30g melted, 170g kept cold and cubed)
For the Lemon Filling:
- Fresh lemon curd: 1 cup (260 g) (or a homemade blend of fresh lemon juice, sugar, eggs, and a touch of flour)
Instructions (Step by Step)
- Preheat the Oven: Preheat your oven to 350°F (180°C / 160°C fan-forced). Line an 8×8-inch or 9×9-inch square glass baking dish with parchment paper, leaving a slight overhang for easy removal.
- Mix the Dry Ingredients: In a large mixing bowl, whisk together the all-purpose flour, sugar, and salt.
- Cut in the Butter: Grate or cut the cold, cubed butter into the flour mixture. Use your fingertips or a pastry blender to work it in until the texture resembles coarse breadcrumbs. Stir in the slightly cooled melted butter until the mixture easily forms clumps when squeezed.
- Form the Base: Reserve about one-third of the crumb mixture for the topping. Press the remaining two-thirds firmly and evenly into the bottom of your prepared glass baking dish.
- Initial Bake: Bake the crust for about 20 minutes, or until the edges are just starting to turn light golden brown.
- Add the Lemon Filling: Remove the crust from the oven and let it cool for about 10 minutes. Spread the lemon curd evenly across the warm shortbread base using an offset spatula.
- Add the Streusel Topping: Scatter the reserved shortbread crumbs unevenly over the lemon layer, creating a combination of small and large clumps.
- Final Bake: Return the pan to the oven and bake for an additional 25 to 30 minutes, until the crumb topping is lightly golden and set.
- Cool Completely: Allow the bars to cool completely at room temperature, then chill in the refrigerator for at least 2 hours before slicing into neat squares.
Service Suggestions
- Dusting: Lightly dust the top with powdered sugar just before serving for an elegant bakery finish.
- A La Mode: Serve chilled or slightly warmed with a generous scoop of vanilla bean ice cream or a dollop of fresh whipped cream.
- Beverage Pairing: Enjoy alongside a hot cup of Earl Grey tea, morning coffee, or a cold glass of iced lemonade.
Storage Tips
- Refrigeration: Store the cut bars in an airtight container in the refrigerator for up to 5 days. Keep layers separated with parchment paper to preserve the crumb topping.
- Freezing: To freeze, wrap individual uncut or cut squares tightly in plastic wrap and place them in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before serving.
FAQs
- Can I use bottled lemon juice? Freshly squeezed lemon juice is strongly recommended. Bottled juice often contains preservatives that lend a metallic or artificial taste, whereas fresh lemons provide a vibrant, authentic citrus punch.
- Why did my crumb topping sink into the filling? If the crumb mixture is too heavy or wet, or if it’s dropped onto a boiling-hot filling too aggressively, it can submerge. Make sure to keep the reserved topping dry and flaky, and gently scatter clumps over the surface.
- Do I have to use a glass dish? Glass baking dishes are ideal for even heat distribution and prevent the citrus from reacting, but a light-colored metal pan of the same dimensions will also work.
Conclusion
These Lemon Crumb Bars are a true crowd-pleaser, combining a buttery crunch with a bright, mouth-puckering citrus center. Easy to prep and stunning to serve, they are bound to become a staple in your dessert rotation!
